Hark Introduces Handoff AI Agent
Hark, an AI startup established by Brett Adcock, has launched its first product, Handoff. This computer use agent (CUA) is designed to autonomously perform tasks by navigating the open web, including ordering dinner on platforms like DoorDash, booking flights on United and Delta, or messaging job candidates on LinkedIn.
Handoff operates by spinning up a dedicated virtual computer for each request, complete with its own browser, file system, and terminal. It is capable of interacting with websites that lack official APIs, such as Target, Walmart, and OpenTable, by analyzing website structure and visual data to identify buttons and input fields.
Performance and Cost Claims
Hark states that Handoff achieved the top score on the Online-Mind2Web (OM2W) benchmark, a third-party evaluation for web agents. Handoff recorded a score of 97.7, exceeding OpenAI's GPT 5.4 (92.8), Anthropic's Claude Opus 4.8 (84.1), and Google's Gemini 2.5 Pro (69).
The company also claims to offer competitive pricing for its model, citing $0.18 per million input tokens and $2.37 per million output tokens. This is presented as less than one-tenth the token price of models like GPT 5.5, which are listed at $5 and $30 respectively. Handoff also reports a per-turn model latency of 0.8 seconds.
Company Background and Funding
Hark, founded earlier this year by serial entrepreneur and roboticist Brett Adcock, secured $700 million in Series A funding in May. Sign-ups for Handoff are currently open to the public, with the initial release of Hark's software platform planned for later this month.
For this initial release, Hark is utilizing a post-trained model, with plans to implement pre-training later in the year.
